    When comparing the symmetry type of two objects, the origin is chosen for each separately, i.e., they need not have the same center. Moreover, two objects are considered to be of the same symmetry type if their symmetry groups are conjugate subgroups of O(3) (two subgroups H 1, H 2 of a group G are conjugate, if there exists g ∈ G such that H 1 = g −1 H 2 g).

    During Star Trek: The Original Series, he served as Gene Roddenberry's right-hand man, who managed the show along with John D. F. Black, Herbert F. Solow, D.C. Fontana, and Gene L. Coon. Justman was reportedly the first to call Gene Roddenberry "The Great Bird of the Galaxy," drawn from a throwaway line from the original series episode "The Man ...

    Analysis : develop a model of the desired behavior; Design : create an architecture; Evolution: for the implementation; Maintenance : for evolution after the delivery; The micro process is applied to new classes, structures or behaviors that emerge during the macro process. It is made of the following cycle: Identification of classes and objects

    The book treats mostly 2- and 3-dimensional geometry. The goal of the book is to provide a comprehensive introduction into methods and approached, rather than the cutting edge of the research in the field: the presented algorithms provide transparent and reasonably efficient solutions based on fundamental "building blocks" of computational ...

    The phrase was originally said by Captain James T. Kirk (William Shatner) in the original Star Trek series. "Where no man has gone before" is a phrase made popular through its use in the title sequence of the original 1966–1969 Star Trek science fiction television series, describing the mission of the starship Enterprise.

  8. Passive data structure - Wikipedia

    en.wikipedia.org/wiki/Passive_data_structure

    A PDS class has no user-defined copy assignment operator, no user-defined destructor, and no non-static data members that are not themselves PDS. Moreover, a PDS class must be an aggregate, meaning it has no user-declared constructors, no private nor protected non-static data, no virtual base classes [a] and no virtual functions. [4]

  9. Numerical 3-dimensional matching - Wikipedia

    en.wikipedia.org/wiki/Numerical_3-dimensional...

    The numerical 3-d matching problem is problem [SP16] of Garey and Johnson. [1] They claim it is NP-complete, and refer to, [2] but the claim is not proved at that source. The NP-hardness of the related problem 3-partition is done in [1] by a reduction from 3-dimensional matching via 4-partition. To prove NP-completeness of the numerical 3 ...
